Anticoagulant activity of Triatoma infestans and Panstrongylus megistus saliva (Hemiptera/Triatominae)

Acta Tropica, 1996
Salivary gland extract of Triatoma infestans prolonged thrombin time, prothrombin time, and activated partial thromboplastin time, while salivary gland extract of Panstrongylus megistus delayed thrombin time and activated partial thromboplastin time. However, saliva of P.

Experimentally Induced Heat-Shock Tolerance inPanstrongylus megistus(Hemiptera: Reduviidae)

Journal of Medical Entomology, 2001
The survival and molting incidence of fifth-instar nymphs of Panstrongylus megistus (Burmeister, 1835), a vector of Chagas' disease, were investigated following sequential heat shocks in which a mild shock (35 or 40 degrees C, 1 h) preceded a more drastic one (40 degrees C, 12 h). The shocks were separated by 8-, 18-, 24-, or 72-h periods at 28 degrees

Aggregation behaviour in Panstrongylus megistus and Triatoma infestans: inter and intraspecific responses

Acta Tropica, 2002
We tested the aggregation response to inter and intraspecific chemical signals in Panstrongylus megistus and Triatoma infestans. As previously described for T. infestans, larvae of P. megistus significantly aggregated on papers impregnated with their own excrement and on papers marked with cuticular substances deposited on surfaces on which these ...

Blockage of Embryonic Development in Panstrongylus Megistus by Juvenile Hormone Analogues

International Journal of Tropical Insect Science, 1984
The effect of five juvenile hormone analogues (JHAs) on the embryonic development of Panstrongylus megistus, a vector of Chagas’ disease, was studied. Four compounds, N-(2,5-dich-loropheny])-3,7-dimethyl-2-6-octadienylamine, N-(5-chloro-2-rnethylphenyl)-3,7-dimethyl-2,6-octadienylamine, 3,7-dimethyl-6,7-epoxy-1-(3,4-methylenedioxyphenoxy)-2-nonene, and

Differences in saliva composition among three Brazilian populations of Panstrongylus megistus (Hemiptera, Reduviidae)

Acta Tropica, 1999
Comparisons of electrophoretic profiles of triatomines (Panstrongylus megistus) from the Brazilian states of Bahia (BA), Minas Gerais (MG) and Santa Catarina (SC) revealed differences in the composition of the saliva between the three populations. A phenogram constructed on the basis of the most representative electrophoretic banding patterns allowed ...

Studies of Repellents Against Panstrongylus Megistus (Hemiptera: Reduviidae) in Brazil

Journal of Medical Entomology, 1980
Various known and new candidate repellents and compounds, including extracts of Brazilian plants, were tested to determine their possible use as repellents against Panstrongylus megistus . Repellents were not sufficiently effective for practical use as skin treatments.

Octosporea carloschagasi n. sp., a microsporidian associate of Trypanosoma cruzi in Panstrongylus megistus

Zeitschrift f�r Parasitenkunde, 1972
Some protozoan forms from Panstrongylus megistus that Chagas had incorporated into his original description of Trypanosoma cruzi are compared with schizogonic and sporogonic stages of the microsporidian Octosporea muscaedomesticae. On the basis of the evidence presented O. carloschagasi n. sp. is described.
